NCT07094529

Brief Summary

This study will offer two study interventions designed to bring on a mild low blood sugar (capillary blood glucose result 3.0 to 3.8 mmol/L), in order to study the effectiveness of each study participant's personal choice of treatment and first recheck time. The two study interventions that the participant can choose to complete (one or both interventions). Based on each participant's own experience with hypoglycemia treatment or their preferences, the participant can choose one of 4 simple carbohydrate treatment quantities, and choose one of 4 capillary blood glucose recheck times.

Outcome Measures

Primary Outcomes (1)

  • To determine feasibility to recruit an average of 8 patients per month at the study site (The Ottawa Hospital Diabetes clinics) for study protocol performance.

    Average number of patients recruited per month is determined by 60 patients (the target recruitment number) for each study intervention, divided by the number of months that it took to complete the recruitment.

    12 months

Secondary Outcomes (1)

  • To assess the percentage hypoglycemia resolution for people living with type 2 diabetes based on their personalized choice of treatment and first recheck time.

    12 months

Study Arms (2)

Recumbent Exercise Bike to induce mild hypoglycemia

EXPERIMENTAL

The participant rides the recumbent exercise bike at their preferred speed and records the distance travelled until there is onset of mild hypoglycemia.

Behavioral: Recumbent Exercise Bike to induce mild hypoglycemia

Delaying food to induce mild hypoglycemia

EXPERIMENTAL

At the study visit, in front of the study nurse, the participant takes their usual clinical care dose of sulfonylurea or basal insulin. If the participant's usual clinical care includes insulin with a rapid-acting component, then its dose is reduced based on the study protocol.

Behavioral: Delaying food to induce mild hypoglycemia,

Interventions

The participant rides the recumbent exercise bike at their preferred speed and records the distance travelled until there is onset of mild hypoglycemia, determined by capillary blood glucose test result 3.0 to 3.8 mmmol/L. Based on each participant's own experience with hypoglycemia treatment or their preferences, the participant can choose one of 4 simple carbohydrate treatment quantities: 8 grams, 16 grams, 20 grams, 32 grams The participant can choose one of 4 capillary blood glucose recheck times: 15 minutes, 20 minutes, 25 minutes, 30 minutes.

Recumbent Exercise Bike to induce mild hypoglycemia

At the study visit, in front of the study nurse, the participant takes their usual clinical care dose of sulfonylurea or basal insulin. If the participant's usual clinical care includes insulin with a rapid-acting component, then its dose is reduced based on the study protocol. No food intake (water is allowed) until there is onset of mild hypoglycemia, determined by a capillary blood glucose test result 3.0 to 3.8 mmol/L. Based on each participant's own experience with hypoglycemia treatment or their preferences, the participant can choose one of 4 simple carbohydrate treatment quantities: 8 grams, 16 grams, 20 grams, 32 grams The participant can choose one of 4 capillary blood glucose recheck times: 15 minutes, 20 minutes, 25 minutes, 30 minutes.
